What is MBT?

MBT stands for Masai Barefoot Technology, a rocker-bottom shoe design intended to mimic walking on soft ground. It was created by the Swiss inventor Karl Mueller and became a well-known health and fitness shoe concept in the 2000s.

History

According to Wikipedia, Mueller founded Swiss Masai in 1996 to market the shoe concept, a company now called Masai Marketing and Trading AG, and a patent reference for the design dates to 1998. He left the company in 2007 on amicable terms, while a Moneycab interview says he left in 2006 after disagreements with minority shareholders over a softer next-generation design. He then founded kybun to market an air-cushion shoe.

The same interview states that MBT filed for bankruptcy in May 2012 and that its patents, licences and infrastructure then belonged to a Singapore entrepreneur. The sources consulted do not describe the brand's current owner, so no group is named in this profile.

Products and positioning

MBT shoes were built around a curved sole and were marketed as a way to train posture and muscles during everyday walking. Kybun's founder has said that the two product concepts are different, since kybun uses a soft air-cushion sole rather than a rocker sole.

Why it matters

MBT is a case study in how a single technical concept can build a global footwear brand quickly, and how dependent such a brand can be on its inventor, its investors and its patents. Its inventor's later brand, kybun, is part of the kybun Joya Group.
